java - 无效类异常

Question

我的应用程序运行正常，在我将名字更改为英文版本后，我得到了 InvalidClassEception 。我该如何解决？我找到了一些有关它的信息，但我不明白如何解决它。一些帮助？这是我的代码:

public class Serializare {
    //private static final long serialVersionUID = 1L;
    public void serialize(Bank bank, String fileName) {
        try (ObjectOutputStream out = new ObjectOutputStream(
                new FileOutputStream(fileName))) {
            out.writeObject(bank);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

    public Bank deserializeW(String fileName){
        Bank bank = null;
        try (ObjectInputStream in = new ObjectInputStream(new FileInputStream(
                fileName))) {
            bank = (Bank) in.readObject();
        } catch (IOException | ClassNotFoundException ex) {
            ex.printStackTrace();

        }
        return bank;
    }
}

public class Bank implements BankProc, Serializable {

    /**
     * 
     */
    //private static final long serialVersionUID = -7029959057180382645L;
    private Hashtable<Integer, Account> bank;

    ...

}

我的错误是

java.io.InvalidClassException: Bank.Bank; local class incompatible: stream classdesc serialVersionUID = -7029959057180382645, local class serialVersionUID = -2329932680711902869

Answer 1

您尝试使用给定的 serialVersionUID 序列化一个类，然后使用另一个不同的类对其进行反序列化。

参见what is a serialVersionUID .
